Application filed February 21, 1906. Serial No. 302,185.

citizen of the United States, residing at 482 Diamond street, iittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Im rovements inWeather-Strips, of which the ollowing is a specification, reference i being had therein to the accompanying drawings.

This invention relates to improvements in weather-strips, and has for its object the provision of a device of this character comprising coacting metal members adapted to have relative slidin l engagement when used in connection wit windows or to be freely separated and rengaged when used in connection with doors, one of the members of the strip being mounted, whereby it may move bodily relative to its, primary or initial position to maintain the normal operative engagement between he members, while accommodating for shrinkage or warping of the wooden parts,

such as the windows or doors or their frames, and a yieldable packinfy adapted to be inter# posed between the shiftable member of the strip an'd its frame or the part towhich it may be attached, whereby said member', ythough shiftable, as stated, is sealed at its base or attaching portion to prevent passage of air, dust, water, &c., thereunder. Convenient embodiments of the invention are illustrateli in the accompanying drawin s, and the novel details and arrangement of t e several parts will be apparent from the detailed description hereinafter contained when read in connection with said drawings.

In the drawings, Figure 1 is a fragmentaryl perspective view of awindow-frame and sash, showing m improved weather-strip applied thereto. ig. 2 is an enlarged transverse sectional view through a sash, strip, and frame. Fig. 3 is a detail pers ecti've view of the several arts of the strip etached and separated;

. and ig. 4 is a view similar to Fig. 2, showing an embodiment of the invention wherein the y strip is usedin connection with 'a swinging door or window and its frame.

Referring more specifically to the drawings and for the present with reference to the first threeviews thereof, A; designates a'sliding sash, B awindow frame or casing, and

C the groove or runway of the frame, within which the sash'works u and down in the usual manner. In-the e ge of the sash, pref- 'erably the surface c thereof which opposesthe base c of the runway, I form a groove D. In this groove I mount a spring-metal insert E, the same in cross-section being ap roximately U-shaped, the free portions or anges of which converge-toward each other, whilev the connecting edge thereof srounded, as shown very clearly in Fig. 2. This strip is movably secured in place, whereby it mayl rock or shift bodily in a lateral direction through the medium of tacks e, loosely engaging the rounded connecting edge or bendv' e thereof and embedded in the material of' the sash. The viianges of the insert just'defined have a permanent tendency to s ringin orconvergetoward each other, where y their outer edges may constantly im inge upon opposi'te sides of a flange or rib' arranged to pro]ect into the groovef formed between the flanges of the insert, said rib or flange be-l ing in turn mounted in the base of the runway or groove ofthe sash-frame in any con; venient manner, conveniently by means 'of base-flangesf, tacked down or heldin place by overhan ng ortions of the'sash-frame.

shown, t ese ase-lian es and the sealinrib or iiange are formed o ysheet metal dou led upon itself after'the 1fashion well known inv this art. x

It will be noted that the enga ement of the ilanges of the spring-insert wit the sealingv rib or flange is substantially a line contactat each side ofthe latter whereby rubbing frictional contact incident to the raising and lowering of the sash is minimized, while at the same time the lsealing elfect secured by the co eration of said insert and the sealing .rib

or ange will be maintained, notwithstanding the warping or shrinkage of the sash or frame,

until the sealin ri or flange 'is 'entirely withdrawn from t e s ace Within the insert, and the possibilities o any such separation are extremely' remote, and as a matter of fact it is doubtful if such a condition ever arises.

The special ti e or rib shown in the drawings is peculiar y adapted for use in connec` rts become so separated that the vtion with my spring-insert, inasmuch as such rib has a bul ed or laterally-enlarged ,ed e,

whichwhen 1t e sash moves away from t e l frame incident to shrinka e increases vthe,

sealing contact between t e edges vofjthe spring-metal insert and the side Walls .of the rib or ilange, as will be readily appreciated..

reg

Referring now to Fig. 4, Wheretbe members carrying the spring-insert and the seeling rib or flange ere caused to approach or recede one relative to the other, l represents n swinging sash or door, and il its treme, the insert being inr-licated et 4 und the sealing rib or flange at 6, and in this connection it is to be noted that the free edges oi' the insert ere rounded or turned outwardly, es at 5, to facilitate the entrance ol the sealing rib or flange therebetween when the swinging sash or door is closed.

In both .of the forms of strip hereinbeiore described it will be noted that owing to the rounded configuration ol' the connectingr portion of the insert und the loose fitting of the securing-tricks said iiisert muy have n. liniited lateral tilting or rocking,V movement to pre'- scrve its normal operative relation to the sealing-strip, notwithstanding the shrinkage or warping of thewooden parts of' the w1ndow, treme, te.

'lhc i'orn'niti'on of'pnrts und combinations thereof thus fur set lorth herein will not be broadly claimed in this zipplicetion, beceuse they constitute the subject-mettcr of my co pending a plicntionior patent, Serial No. 256,703, ii ed April 2l, 1905. The characteristic feature of the present invention resides inthe matter now to be pointed out. Owin to the loose mountintr ot the springmet-e insert to ermit its bodily movement or shifting in. e eterni directioi'i, the contact of the rounded or connecting portion ol` this insertwith the buse of its groove is obviously not perfect so lar :is sealing the space therebetween is concerned, und in order to provide un nir und weiter tight seul :it this point l interpuso between 1h(x buse ol the groove und the rounded connecting )ortion oi.' the insert n l'elt strip or other yielduble pecking 7, through which theI securing-turks of the insert pass und nre driven homc suliciently to omiso the rounded connectingr portion of the insert to become embedded in seid pecl/ring und form u. sealing; engnigement therebetween, while at the sume time oll'ering; no perceptible interference to the lateral or rocking movei'nents oll seid insert.

()wing to the converging relation oi the flanges of the insert and the substantially parallel relation ot the .wells of the groove in which the sume is mounted, there vis abundent space eilorded for thc rorkingl or shitting of the inserttowztrd either side of the groove. Y Y

Having thus described the invention, what is claimed as new, and desired to be secured by'Letters Potent, is f l. The combination with a treme member provided with a runwey und i sash member mountedto cooperate with sind runwity, one of -seid members being provided with u groove, of e wentliei-stiip interposed between sind members comprising two opposi im,r sheet-metel parts, one 0l seid ports heving e securingnllange and nn outwerdly-ex tendiner rib arranged to project into seid groove, :ind theinither oi' said parts comprisintr e pair of connected spring-tieners euch free fi-t 'its outer edge und adapted to confort with the side surfaces of snid rib, th connecting portion intermediate seid springi'lenges being rounded laterally, means passing through seid rounded connected portion l'or securing seid s )ring-flanges in platee whereby their i'ree edges ere freely movable within said groove and also whereby seid s ring-flanges may bodily rock in e lateral direction, the side walls of the groove beineY spaced eport from the free edges of the spring-flanges whereb;r :imple space is provided to permit said iiiuiges to spring' or rock laterally without interterencerom seid side wells, und e senlii'ig-peolring interpoi-ied between the rounded connecting portion of the springdlenges end the member to 'which 'it-is attached.
